Tektronix TDS 400 Digitizing Oscilloscopes are portable instruments suitable
for use in a variety of test and measurement applications and systems. Key
features include:
H Four input channels on the TDS 420 and TDS 460 (two input channels on
the TDS 410), each with a record length of 500 to 15,000 points and 8-bit
vertical resolution. (Option 1M extends the maximum record length to
60,000 points.)
H Simultaneous acquisition of waveforms in all channels at the maximum
digitizing rate of 100 Megasamples/second. All channels acquire at the
full analog bandwidth of 150 MHz (TDS 410 and TDS 420) or 350 MHz
(TDS 460) and all have the same features.
H Video triggering capabilities (with Option 5, Video Trigger).
H Full programmability and printer/plotter output.
H Advanced functions, such as continuously updated measurements.
H Specialized display modes, such as infinite and variable persistence.
H A unique graphical user interface (GUI), an on-board help mode, and a
logical front-panel layout which combine to deliver a new standard in
usability.
H Advanced waveform math (with Option 2F, Advanced DSP Math). Com-
pute and display the integral of a waveform, the differential of a wave-
form, and the FFT (Fast Fourier Transform) of a waveform.

This manual is divided into sections, such as Specifications and Theory of Operation. Further, it is divided into subsections, such as Product Description and Removal and Installation Procedures.
Sections containing procedures also contain introductions to those procedures. Be sure to read these introductions, because they provide information needed to do the service correctly and efficiently. The following is a brief description of each manual section.
■ Specifications — contains a product description of the digitizing oscilloscope and tables of the characteristics and descriptions that apply to it.
■ Operating Information — is this section. It includes a description of how this manual is structured, as well as general information and operating instructions at the level needed to safely power up and service this oscilloscope. A statement of the service strategy that this manual supports, as well as instructions for shipment of the digitizing oscilloscope, are found in this section.
■ Theory of Operation — contains circuit descriptions that support general service and fault isolation.
■ Performance Verification — contains a collection of procedures for confirming that this digitizing oscilloscope functions properly and meets warranted limits.
■ Adjustment Procedures — contains a collection of procedures for adjusting this digitizing oscilloscope to meet warranted limits.
■ Maintenance — contains information and procedures for doing preventive and corrective maintenance of the digitizing oscilloscope. Instructions for cleaning, for module removal and installation, and for fault isolation to a module are found here.
■ Options — contains information on servicing any of the factory-installed options that may be present in your oscilloscope.
■ Electrical Parts List — contains a statement referring you to the Mechanical Parts List, where both electrical and mechanical modules are listed. See below.
■ Diagrams — contains a block diagram and an interconnection diagram useful for isolating failed modules.
■ Mechanical Parts List — includes a table of all replaceable modules, their descriptions, and their Tektronix part numbers.
